Professional electrification system for double bass, equipped with preamp and double pickup for keyboard and bridge. Realized in collaboration with the famous Didi Beck Dispasser, the SH-965-NFX is the most versatile pickup system in the world for Rockabilly and Psychobilly. The system consists of the famous Shadow SH951 for the bridge and a Shadow SH250E to be installed under the keyboard. The PREAMP is equipped with numerous separate tone controls for the two pickups with which to sculpt its sound and has two independent outputs for the SH951 and the SH250E. Phase reversal and the Subsonic Switch allow you to prevent feedback problems, while the chromatic tuner allows easy and fast tuning on internships. Powered via 9V battery (not included).
